The transmission device is configured to shift a transmission ratio of a human-powered vehicle. The first controller is configured to control the transmission device. The first communicator is configured to perform communication with a drive unit for a human-powered vehicle. The drive unit includes a motor configured to apply a propulsion force to the human-powered vehicle. In a case where the first controller shifts the transmission ratio. The first controller is configured to control the first communicator so that the first communicator sends first information to the drive unit in a case where the first controller shifts the transmission ratio. The first information includes at least one of information related to a shifting time of the transmission ratio and information related to a shifting period of the transmission ratio.
